Title: Semiconductor storage circuit
Inventor: OKAJIMA YOSHINORI
IPC: G11C11/34
Filed: 1982-12-29
Abstract: PURPOSE:To realize fast processing and to prevent the base voltage of a selecting transistor (TR) from rising unnecessarily by dividing a memory cell group into block and selecting a block by the initial-stage bit driver and a bit line couple by the trailing-stage driver. CONSTITUTION:The cell group of a memory 33 is divided into a memory blocks MB1-MB5, etc. Then, the 1st-stage bit driver 31 selects the blocks MB1-MB5 and the 2nd-stage bit drivers DRV21-DRV25 select bits couples of the corresponding locks MB1-MB5 through selecting TRs. Therefore, the bit line couples in charge of a common bit driving line are reduced in number and junction capacity is reduced to speed up the operation; and the total amount of base currents of selecting TRs in unselected states is also reduced to eliminate the need to raise unnecessarily the base voltage of a selecting TR in a selected state.

Title: Beam index type cathode-ray tube
Inventor: HIRAI YOSHINORI
IPC: H01J29/32
Filed: 1984-10-31
Abstract: PURPOSE:To obtain a picture image without cloudy colors, by furnishing a photoindex phosphor in which neighboring phosphors don't irradiate simultaneously or the photoindex phosphor exercises light absorbing function. CONSTITUTION:The strips of two color irradiating phosphors, neighboring with the stripe of a photoindex phosphor 4, are made of phosphors with an insensible or a dully sensitive phosphor to the light from the photoindex phosphor. And, phosphors 3B of blue color irradiating are avoided to place neighboring with the photoindex phosphor 4, but phosphors 3R and 3G of red and green colors irradiating are placed neighboring with the photoindex phosphor 4. In this case, as phosphors 3R and 3G, are used Y2O3:Eu red and ZnSiO3:Mn green, for example, which don't irradiate when receiving light from the photoindex phosphor. Therefore, when electron beams hit the photoindex phosphor, the neighboring phosphors don't irradiate simultaneously, and the index phosphor exercises light absorbing function, resulting in no mixture of cloudy colors.

Title: Liquid crystal device
Inventor: HANAMI TAKAYOSHI
IPC: G02F1/1337
Filed: 1994-09-27
Abstract: PURPOSE: To turn a non-image part into an achromatic color without depending on temperature by orienting liquid crystal molecules in the non-image part vertically toward an electrode substrate. CONSTITUTION: In substrate 2a, 2b, electrodes 3a, 3b are arranged individually, and oriented films 4a, 4b are applied and formed on their respective surfaces. Between the substrates 2a, 2b, a nematic liquid crystal 5 having positive dielectric anisotropy is sealed. The oriented films 4a, 4b for the electrodes 3a, 3b are formed by applying polyimide group horizontally oriented films by means of a printing method or a spin coating method and rubbing them. Then, the horizontally oriented film 4b toward a non-image part of the electrode 3b is removed, and subsequently, a polyimide group vertically oriented film is formed by a printing method.  In this constitution, light incident on the non-image part is directly transmitted without generating interference of light, since the liquid crystal molecules are oriented vertically to the substrates, and as a result, the non-image area exhibits an achromatic color.

Title: Vertical magnetic recording medium
Inventor: KONISHI AKIO
IPC: G11B5/73
Filed: 1984-11-02
Abstract: PURPOSE:To form a vertical magnetic recording medium into a structure with which a lubricant is hardly strippable and to improve the durability of said medium by forming fine ruggedness on an alloy film on the surface and coating a lubricant on the rugged surface. CONSTITUTION:A cobalt-chromium film 2 is formed on a flexible non-magnetic substrate 1 of the vertical magnetic recording medium a1. The fine ruggedness 6 in a 10Angstrom -100Angstrom  range is formed on the surface of the film 2 and the lubricant 3 is coated on the rugged surface. The contact area between the film 2 and the lubricant 3 is thus increased and the lubricant 3 is captured to the rugged surface of the alloy, by which the lubricant is made hardly strippable. The problem of stripping is therefore obviated even if the degree of the tight contact of the main magnetic pole is increased. The durability is thus remarkably improved.

Title: Label printer
Inventor: YONEYAMA KAZUO
IPC: B41J11/42
Filed: 1990-08-31
Abstract: PURPOSE:To improve reliability and operability of a device and miniaturize and lighten the device without an operation for adjusting the position of a light sensor by providing the light sensor for detecting a label of a label sheet on one of sheet guides. CONSTITUTION:In a label printer 1, while a knurled screw 7 is operated manually so as to make a space between sheet guides 2 and 3 correspond to the width of a label sheet, a light sensor 12 will face a side edge of the label sheet automatically as it is attached to the sheet guide 3. That is, in the label printer 1, since the light sensor 12 moves to the position facing the side edge of the label sheet automatically by adjusting the space between the sheet guides 2 and 3 corresponding to the width of the label sheet, an exclusive mechanism for moving the light sensor 12 is unnecessary and an operation for adjusting the position of the light sensor 12 is unnecessary, either. Accordingly, in this label printer 1, the light sensor 12 can be positioned automatically with a simple structure, thereby improving reliability and operability of the device, miniaturizing and lightening the device.

Title: Automatic receiving system
Inventor: UTASHIRO SHINOBU
IPC: H04M11/00
Filed: 1983-12-08
Abstract: PURPOSE:To shorten the response time of automatic receiving by validating the initially detected signal when the succeeding signal is a prescribed call signal even if the original detected signal is not the prescribed call signal. CONSTITUTION:The initial signal sent from an exchange is detected by a call signal pickup circuit 3 through a circuit connecting terminal 1 and inputted to an integrating circuit 4. An output from the integrating circuit 4 is binary-coded by a dinary-coding circuit 11 and then applied to a counter 12. When the output from the counter 12 is supplied to a counter 6 through a gate circuit 14, the counter 6 starts to count up, a timer circuit 15 starts to be driven. A signal length measuring circuit 5 measures the envelope length of a terminated signal. When the successively detected signal is a prescribed call signal even if the originally detected signal in not the prescribed call signal, a call signal confirmation detecting signal is outputted from the counter circuit 6 to a facsimile device body 8 to turn the facsimile device to automatic receiving state.

Title: Polarization type differential refractometer
Inventor: TOKIEDA TSUNEMI
IPC: G01N21/41
Filed: 1982-12-29
Abstract: PURPOSE:To enable stable and exact quantitative measurement by controlling the quantity of the output light from a light emitting element in such a way that the total quantity of the light received in a photodetector is made constant. CONSTITUTION:An added voltage A1(Va+Vb) is supplied to the input terminal of an integrator 15, and the value thereof is integrated and controlled so as to be made always equal to a set voltage Vr. When the voltage A1(Va+Vb) exceeds the voltage Vr, charging current flows from an integrating resistor R to an integrating capacitor C, thus resulting in the decreased output voltage V0 of an integrator 15 and the decreased base current of a transistor 16 controlled by the output voltage V0 of the integrator 15. The decrease in the base current induces a decrease in the emitter current of the TR16, and the quantity of the light outputted from a light emitting element 2 is decreased. The decrease in the quantity of light is detected by photodetectors 8a, 8b, and the voltage A1(Va+ Vb) decreases. On the other hand, when the voltage A1(Va+Vb) decreases to the voltage Vr or below, the voltage A1(Va+Vb) increases by the reverse operation. The voltage A1(Va+Vb) is thus so controlled as to be kept always equal to the voltage Vr and therefore the total quantity of the light L received in a photodetector 8 is made always constant.
